Eclipse：使用导入项目的Struts Actions

Question

I have 2 Dynamic Web Projects:

• cms
• Demo

Using Struts2 I want project Demo to use actions of the project CMS.

In Demo's "Java Build Path" configuration, in the "Project" tab I added the CMS project.

Now in the struts.xml of Demo I have

<action name="hello" class="cms.helloworld.action.HelloWorldAction" method="execute">

where the package cms.helloworld.action is a CMS project package.

Eclipse see it correctly, in fact with ctrl + right click on the class name it open me the correct Java file.

Now, in Demo's deployment assembly configuration I added the CMS project, so that also Tomcat can find the relative classes.

But when I run the project on tomcat server the log says:

Grave: Dispatcher initialization failed Unable to load configuration. - action

Caused by: Action class [cms.helloworld.action.HelloWorldAction] not found

It can't find the action on CMS project.

What am I doing wrong?

You should merge two projects into one, and put struts.xml into src . As far as I remember Eclipse is not able to reference another web project as module, ie you have to copy WebContent manually during build, that is why you shouldn't reference other web projects and a main project is not a Java EE project. You should also take into account that Tomcat server is not able to handle Java EE projects if you decide to develop one, for this purpose you should choose full featured Java EE Application server. Even that you have an option to only one web module.
